Everyone has different hairgrowth u'res might be thick coarse hair, people with thin/scanty eyebrows usually need threading/waxing after 3-4 weeks. "Phitkari" or alum (wet) rubbed over the area that u've just threaded/waxed will reduce the hairgrowth. The best way to stay groomed is tweeze the stray hair that grow back. I wudn't recommend electrolysis this close to u're wedding incase of any reactions.
hmm i dunno. she has 3 months and electrolysis reactions are temporary. if she was inclined she could go for a consultation and see what kind of reaction she gets.
speaking from experience and being a paranoid person, i was expecting everything to go wrong before i started my treatments but thank god everything has been wonderful. i even go to my treatments before work; there is a little redness immediately after but it fades by the time i arrive at work. i've never experienced any kind of temporary scarring even when my electrologist has had to be aggressive with a stubborn hair. but she is very good and experienced.
consider it for afterwards though, it will make such a difference with one less thing to worry about and deal with.
